I doubt that CASA has the expertise to complete the process and produce a satisfactory outcome.
The correctness of your view depends upon the timeframe in which the process is supposed to be completed and what constitutes a satisfactory outcome. Neither of those parameters has ever been defined, and no one has a hip pocket nerve connected to them.
CASA has the expertise to have completed the process 3 times over, in satisfaction of whatever differing criteria anyone wanted to choose. The real problem is that despite what its critics might think, the folks in CASA aren't stupid. The people in CASA know perfectly well when there's a policy decision to be made, and they know perfectly well that the people who are supposed to make those decisions are hoping that some other muggins will make them instead.
The recent history of regulatory 'reform' is a litany of Ministers, Ministerial staffers and advisors, dabblers and others, who want someone
else to make and take responsibility for their decisions. The people at the coal face in CASA aren't that dumb.
They say: "Here are your options, here are the risks and benefits of each option, now
you tell us which option
you wish to take, because it is
your decision."
Ouch! That could mean that a CEO, or a staffer or some other politician might be held
accountable for a decision!
We can't have that now, can we.
So, let's just drift around year after year, spouting motherhood statements, and hope that everyone stops noticing the obscene waste of time and money that's left in our wake.
